The Professional Series™ engines were designed to be best-in-class combining power, performance, features, and size. These engines offer consumers and professionals commercial-grade features including easier starting, smoother and quieter operation, increased durability, and longer life. ReadyStart ® is standard on all Professional Series engines.
I have a professional 775 model B&S engine on a self-propelled walk-behind mower. I can't seem to find the owner's manual so that I could get the part number to order.
